Abstract

Non Random Two Liquid model (NRTL) with three different forms of temperature dependant parameters was used to correlate the liquid - liquid equilibrium data for systems of alcohols with alkanes, and alcohols with two ionic liquids: 1-butyl-2,3-dimethylimidazolium tetrafluoroborate ([bmmim][BF4]) and 1-butyl-3-ethylimidazolium tetrafluoroborate ([beim][BF4]). Different temperature dependences of NRTL parameters were tested on thirteen literature experimental liquid - liquid equilibrium data for binary systems.
